The victim appears to be opening a mailbox in the lobby of the Baychester building when the suspect slowly walks up behind her and punches her in the head.

After the woman falls, she is seen struggling with the suspect on the floor before he eventually overpowers and robs her.

The other attacks took place on Wallace Avenue, Holland Avenue and Matthews Avenue — all in Baychester — police said.

The suspect is described as a 5-foot-9 Hispanic man between 25 and 30 years old. He was last seen wearing a white t-shirt, blue jean shorts and a red and black baseball hat.
